Math Moves! Experiencing Ratio and Proportion

Permanent Exhibit

Bigger/smaller, faster/slower, heavier/lighter — use your body to explore ratios in our newest math exhibit! Immerse yourself in a world of shadows, shapes, motion, and sound. Use your body as a unit of measurement by climbing into a huge chair then squeezing in a tiny one to compare your size. Grab a friend, get moving, and watch as your rates of motion are both tracked on a screen. Listen, watch, and feel what happens when you change the pitch and frequency of sounds. Ever wonder how shadows change size? Here you can grow, shrink, match, and measure while discovering connections between shapes, shadows, and sizes.
